example 1

[0735] Example 1. Calculate the kill rate of microorganisms

[0736] Provided below are the steps for calculating the UV intensity required to kill a desired microorganism, and therefore the time to kill, using the compositions, algorithms and methods of the present invention. Here, the required energy doses of UV radiation required for killing factors are provided in Tables 1 to 5 (UV dosage, in μWs / cm 2 )(microwatt / cm 2 ). As shown in Table 9 below, according to the algorithm presented here, to determine the UV intensity (UV dose) on a surface at various distances from the germicidal UV light source, the user will radiate energy (in microwatts per square centimeter at a distance of one meter shown) divided by the intensity factor.

[0743] Example 2. Inhibits the growth of Bacillus subtilis

[0744] In order to determine the effectiveness of the method of the present invention and the efficacy of the UV device of the present invention in sanitizing stainless steel tanks used in the winemaking process, Bacillus subtilis (American Type Culture Collection, ATCC No.: 82TM; Designation: AMC[ ATCC 8037, NRS 315]) kill / growth arrest. Bacillus subtilis forms spores, thereby making it a more UV resistant microorganism than non-spore forming microorganisms. In this experiment, as the UV light source, a 30" SE UV-C lamp (Steri-Aire) was used. Three identical UV lamps were placed on a stand and placed in a helical configuration with each UV lamp at 15 angle set.

[0756] Example 3. Microbial population reduction on stainless steel tanks using UVC (UVT-4 model) versus steam and peracetic acid Disinfection Contrast Efficacy Test

[0757] A comparative efficacy trial of three different tank sanitization methods was conducted at a winery in St. Helena, California (CA). The purpose of this comparative trial was to evaluate the sanitizing efficacy of various sanitizers (steam, peracetic acid (PAA)) and ultraviolet light C (UVC) for the reduction of wine and ambient microbial populations on the interior surfaces of stainless steel production tanks. Trials were performed on four different cans. Briefly, the method of testing was as follows: (i) the tanks were emptied of wine; (ii) pre-treatment microbial swab samples were collected from the ceiling, wall, and floor of each tank; (iii) Tanks were subjected to an appropriate sanitization protocol; (iv) post-treatment microbial swab samples were collected from the roof, walls, and floor of ea...

Abstract

The present invention provides a portable ultraviolet (UV) devices, systems, and methods of use and manufacturing same. Methods of use include methods for UV disinfection and sterilization, more specifically, methods for UV disinfection and sterilization of a container, a room, a space or a defined environment. The portable UV devices, systems and methods are particularly useful for the UV disinfection and sterilization of a container, a room, a space or defined environment used in the food, beverage and dairy industry and in the process of fermentation for an alcoholic beverage. Provided arealso portable UV devices, systems, and methods for inhibiting the growth of one or more species of microorganisms present in a container, a room, a space or a defined environment, preferably for inhibiting the growth of one or more species of microorganisms present on an interior surface of a container, a room, a space or a defined environment.

Description

[0001] Cross References to Related Applications [0002] This patent application is a continuation-in-part of US Application Serial No. 14 / 813,057, filed July 29, 2015, the disclosure of which is hereby incorporated by reference in its entirety for completeness. technical field [0003] The present invention relates generally to compositions, systems and methods for ultraviolet (UV) germicidal, and more particularly to compositions, systems and methods for UV germicidal disinfection of containers, rooms, spaces or defined environments. In more detail, the present invention relates to a portable UV device and its use in a method of sterilizing and disinfecting internal surfaces present in containers, rooms, spaces or defined environments. The invention also relates to a method of manufacturing a portable UV device. Background technique [0004] It is well established that ultraviolet (UV) light has germicidal properties. Specifically, the mechanism by which UV light kills m...
